I'Claim. (c1. res-19o) 5 i There is known for instance from British Patent No. 437,781 valve arrangements for motors comprising a tubular sleeve rotating in the space between a cylindrlc. valve housing, theaxis ofv which is perpendicular or approximately perpendicular to the cylinder axis and a cooled stationary core located in the .valve with the latter. v

The present invention relates to valve devices of this kind and particularly has for its object an embodiment in which no coolingliquid is required for the stationary interior core in the cylindric valve housing, said core in accordance with the present invention being partly cooled' by radiation of heatfrom its exterior surface and partly by means of the mixture'of air and combustibleconducted to the cylinder of themetor whereby the core also serves the purpose of effectively heating the said mixture.

In accordance with the invention a stationary core in the cylindric valve housing is provided with an axial boreextending from one end of the core approximately to midway between the ends thereof, said bore being at its inner end connected with a side opening in the core. Through this axial bore the supply ofair and combustible is conducted, the passage from the said side 'opening'to the intake opening of the cylinder being controlled in a manner known perse by means of the rotating sleeve valve. I

The rest of the core is made solid-and is provided in a known manner with an exterior depression or channel, through which the exhaust gases 'are conducted from the cylinder 'to the exhaust tube also controlled by the rotating sleeve valve. The solid part of the core extends to the exterior surface of the cylinder headwhere it is provided with cooling ribs exposed to the surrounding air.

Experiments" have proved that it is possible inthis manner to obtain an efficient cooling of the core particularly when the same is made of i a metal with good heat conductance such as for instance an aluminum copper alloy with about 15% aluminum.

On the drawing there is'diagrammatically illustrated a form of the invention, Fig. 1 showing an axial section through the cylinder and valve whereas Fig. 2 is a section of the cylinder head and the valve on the line II-.-II of Fig. l.

i is the cylinder and I the cylinder head which .is provided with a transverse channel 3, serving for outlet as well as for inlet purposes although this channel may also be divided in two parts by means of a transverse wall. 4 is the cylindric valve housing and 5 the stationary cylindric core whichis co-axial with-the valve housing. '8 is the rotating tubular sleeve valve which is prohousing co-axially eifected by radiation of heat from the exterior valve with side openings placed in the space be- .nel in the interior stationary cylindrical body,

-power cylinder takes place through an exterior vided in a known manner with openings which during the rotation of the sleeve valve register in correct order. with channel 3. Opening 1 for the outlet is illustrated on Figs. 1 and 2 of the drawing 7 Core 5 has an axial bore from one of its ends so as to form a channel 8 through which the fuel air mixture is conducted to the cylinder, and this channel 8 at its inner end has a side opening 8 which ismade to communicate in a known manner with channel 3 by means of a side open-' ing'in the rotating sleeve valve.

The remaining solid part of core 5 is provided in a known manner with an exterior depression or channel l0 forming the connection with channel 3 and outlet channel when the outlet opening I. of the rotating sleeve valve is in the'position illustrated on Fig; 2.

The cooling of the solid part of the core is 20 cooling ribs l2.

Instead of introducing the air and fuelmixture from the end of the core opposite to the cooling ribs [2, it may also be introduced through a channel from the end of the core carryingthe cooling ribs, the intake channel being then carried past the exterior channel ill of the core.

Having now particularly described and ascertained the nature of my said invention, and in what manner the same is to be performed, 1 declare that what I claim is:

ing in its interior a stationary cylindrical body,

the exterior surface of which is, concentric with the interior surface of the cylindrical valve housing, and also having a rotating tubular sleeve tween the inner surface of the cylindrical valve housing and the interior stationary cylindrical body, the supply of fuel air mixture to the power cylinder taking place through an axial chansaid channel having at its inner end a side opening the communication between which and the power cylinder is controlled by means 01 the rotating sleeve valve, whereas the outlet from the so depression or channel in the cylindrical body, characterized in this that the. said stationary cylindrical body is solid, and besides being cooled by the fuel air mixture supplied to the cylinder,

is provided with cooling ribs at one end of the III .body exposed to the outside air, for cooling the body by conductance of heat. i
